first, find a common denominator (number 7). that number would be 40. now, add your 4 + 1, which is 5. 40 over 5 can be simplified by 5. divide 5 by 5, you get 1. divide 40 by 5, you get 8. your answer would be 8/1
To add or subtract or divide or multiply you need to find a common denominator how much you multiply or divide the denominator you need to multiply or divide tge numerator by the same number
